Biological Production of Lignification Stoppers Available in fields of use other than poplar, eucalyptus, sugarcane and sorghum


The JBEI has developed a technology that overcomes lignin recalcitrance without negatively affecting plant growth and development. The JBEI researchers produced novel monolignols called stoppers that, when incorporated in lignin chains, reduce the incorporation of additional monolignols in the chain. (Monolignols are the building blocks of lignin). As a result, the size and degree of polymerization of the lignin polymer is reduced. This technology is designed to produce the stoppers only in lignified woody tissues, i.e., vessels and fibers, to avoid any interference with plant defense mechanisms against pathogens and UV stress.
